Radical cleric Abu Bakar Bashir seeks review of terror conviction

Radical cleric Abu Bakar Bashir will soon lodge a bid to be freed from jail, a year after he pledged allegiance to the Islamic State (ISIL).

Bashir was acquitted of conspiracy in the 2002 Bali bombings, but is serving 15 years' jail for supporting a terror training camp in Aceh.

The Muslim Defender Team's Mahendradatta confirmed to AAP on Friday that Bashir will seek a judicial review of his case with a Jakarta court within the next two weeks.

"Hopefully next week," he said. "We still need to gather signatures from all the lawyers."

Bashir hopes new evidence will free him.

Considered the spiritual leader of the group responsible for the Bali bombs, Bashir last year pledged his support to ISIL before members of Jama'ah Anshorut Tauhid (JAT), who visited him in central Java's notorious Nusakambangan prison.
